A new feature of the latest MacOS Sierra 10.12 is the option to trash your installer when you are done with it.
At first, this may seem both helpful and smart, after all, who needs all those installers hanging around once the install is done.
But have you wondered why Apple offers to do this?
Space - The Final Frontier
It's simple, one thing that is getting smaller on Macs is the size of the drive you get with your Apple Mac, be that on a desktop or a laptop. Apple may be getting faster, but it comes at a price, and that price is a capacity. As the owner of a Mac Pro Late 2013 with a 256gb drive, I can tell you it does not take long for a few large installers to reduce your drive capacity.
Apple know how many people don't even think about the drive filling up, on a machine with a 1TB drive then the chance of you running out of drive space is less likely. Not so on a smaller drive which once you've installed the OS and some applications does not have a lot of room to spare.
Creative Professionals Take File Managment Seriously
I like many audio professionals have a pretty strong drive regime with different external drives handling audio, video, backups and more - in fact; I have no fewer than 12 drives hanging off my Mac Pro. I also make sure that I do a lot of hard drive housekeeping moving files to the right drive, making sure files and folders are named so that I can find them later and cleaning my desktop each day so all that is left are the hard drive icons. Yes perhaps I'm OCD but my head does a spin when I see a desktop that looks like a folder has exploded leaving several hundred icons on an overly busy desktop background.
Don't Trash It - Move It
Back to Apple offering to trash your installers, it's a half-assed solution, not everyone wants to delete their installers. If there were a preference for the pop up to offer to move them to a predetermined location, which in my case is a drive for all my installers then that would be a complete solution.
Perhaps some helpful app developer like those who create Onyx can come up with that option - then I could maintain drive space and without having to trash my installers or have to think about where to put them.
If you are listening Mr Cook, then this is a small way to still think about the creative professional.
